laboratory headspace gas chromatography Amazon

Seven aldehydes generated from lipid oxidation were studied using headspace solid-phase microextraction coupled to gas chromatography with a flame ionization detector. The extraction efficiency of five commercial fibers was investigated and the influence of extraction temperature, extraction time, desorption temperature, and desorption time were optimized.

Blood-alcohol analysis is a common, important analysis for diagnostic and forensic labs. In addition to the detection of ethanol, other metabolites must be considered, such as methanol or iso-propanol; metabolites interfere with quantifying ethanol in blood samples. A fast, accurate method is required to serve clinical and forensic scientists in these analyses. In this application, headspace

2020/8/6 · Headspace Gas Chromatography methods have been shown to be effective for the determination of ethanol in low concentrations in fermented beverages (6–8, 20–22). A significant advantage of such methods is the ability to minimize the interference of non-volatile constituents through utilizing the headspace injection ( 6 , 22 , 23 ).

Static Headspace–Gas Chromatography: Theory and Practice has longbeen the only reference to provide in–depth coverage of this methodof analysis. The Second Edition has been thoroughly updated toreflect the most recent developments and practices, and alsoincludes coverage of solid–phase microextraction (SPME) and thepurge–and–trap technique.

A portion of the headspace was assayed by gas chromatography with a nitrogen-phosphorus detector. In the heated injector of the gas chromatograph, the propionyl azide undergoes thermal rearrangement, forming ethyl isocyanate, which is subsequently chromatographed and detected.

Determination of Furan in Food by Gas Chromatography-Mass Spectrometry and Headspace Sampling Furan is naturally occurring at low levels in many foods and drinks. Furan consumption is of concern because it been classified by IARC as possibly carcinogenic to humans, based on studies in laboratory
